YES !

there are some really good pictures of this conversion on the german fireboat website [sorry for plug!]. it also means that the lifeboat now sits forward of the main cabin, along with its crane boom.

PS, dont forget the "stern conversion" ! its a must for any dusseldorf! it really help skeep the hull stable in speed turns, check my video out to see for yourself and how effective it is.
I made mine up out of a sheet of thin ply [1.5mm] and again made the triangular supports out of same material, so it wont hurt if you accidentally reverse in to something hard. [ha ha].

no, Ive not converted mine to the later long version, mine is too much fun as it stands, but if I had an oppertunity to grab another cheap secondhand item............... well.......er .............perhaps I would give it a go.

best of luck with yours, dont forget to put the conversion in the build blog, or failing that, "pm" me for more info.
